I have found that it is not unusual for Yamahas or any piano to drop =
that much. It all depends on the environment. Keep track of the pitch =
every time you go out and then use your documentation to sell a =
DampChaser.=20
=20
I've got one Yamaha G1 in a church with a dampchaser that I've tuned =
three times this winter. Each time it was 8 cents flat. Investigation =
showed it to be too close to a heating register.=20
=20
I've never seen a Yamaha or any piano in a school have stable pitch w/o =
a DampChaser installed.

Greetings,

             I have a new customer who is head of a music department. =
Claims she gets all the pianos tuned 3 times a year: All newer (1980+ -) =
Yamahas. One is a grand C7.  I found them all around 8 cycles flat!  I =
find this difficult to fathom. Yet the tuner's card is inside the piano =
with all the dates written on it.=20

              I am really having a hard time believing that these pianos =
were actually brought up to pitch at each tuning. I own a Yamaha. They =
hold a tuning (In my home anyway). The pianos are only used about 10 =
hours a week more than a residence. What could be causing such a drop?=20
